PURCHASE PRICE

Section 2.1. Purchase Price.

The purchase price for the Properties is FIFTY-THREE MILLION, FOUR HUNDRED THOUSAND DOLLARS and NO/100 ($53,400,000.00) (the “Purchase Price”). The Purchase Price, as adjusted pursuant to this Article II and the other applicable provisions hereof, is herein called the "Adjusted Purchase Price". The Adjusted Purchase Price shall be paid by Buyer to Seller under the following terms:

(i) Sixty Percent (60%) of the Adjusted Purchase Price to be paid to Seller in cash at Closing;

(ii) The balance of the Adjusted Purchase Price shall be paid to Seller by Vanguard Natural Resources, LLC (“VNR”), the parent of Buyer, by the issuance of Common units representing LLC interests in VNR (“VNR Units”), such VNR Units to be issued on the Closing Date;

(iii) The VNR Units shall be issued based on Unit Closing Price;

(iv) The number of the VNR Units shall be determined by dividing that portion of the Adjusted Purchase Price payable in VNR Units by the Unit Closing Price; provided if the number so determined contains a fraction, such number shall be rounded upward to the nearest whole number; and

(v) Any adjustments to the Purchase Price shall be made on a proportionate basis between the cash portion of the Purchase Price to be paid on the Closing Date and the portion of the Purchase Price to be paid in VNR Units on the Closing Date.

The VNR Units will be issued subject to the terms and provisions of a Unit Restriction Agreement substantially in the form of the instrument attached hereto as Exhibit 2.1, to be executed by Seller and VNR at Closing.

Section 2.2 Accounting Adjustments.

(a) Appropriate adjustments shall be made between Buyer and Seller so that (i) all expenses (including all drilling costs, all capital expenditures, and all overhead charges under applicable operating agreements, and all other overhead charges actually charged by third parties) which are incurred in the operation of the Properties after the Effective Date will be borne by Buyer, and all proceeds (net of applicable production, severance, and similar taxes) from the sale of oil, gas or other minerals produced from the Oil and Gas Properties after the Effective Date will be received by Buyer, and (ii) all expenses which are incurred in the operation of the Properties before the Effective Date will be borne by Seller and all proceeds (net of applicable production, severance, and similar taxes) from the sale of oil, gas or other minerals produced therefrom before the Effective Date will be received by Seller. It is agreed that, in making such adjustments: (i) oil which was produced from the Oil and Gas Properties and which was, on the Effective Date, stored in tanks located on the Oil and Gas Properties (or located elsewhere but used to store oil produced from the Oil and Gas Properties prior to delivery to oil purchasers) and above pipeline connections shall be deemed to have been produced before the Effective Date (it is recognized that such tanks were not gauged on the Effective Date for the purposes of this Agreement and that determination of the volume of such oil in storage will be based on the best available data, which may include estimates), (ii) ad valorem taxes assessed with respect to a period which the Effective Date splits shall be prorated based on the number of days in such period which fall on each side of the Effective Date (with the day on which the Effective Date falls being counted in the period after the Effective Date), such proration to be adjusted after Closing in the event actual ad valorem taxes are different than projected, with appropriate payments from Seller to Buyer or from Buyer to Seller, as the case may be, and (iii) no consideration shall be given to the local, state or federal income tax liabilities of any party.

Section 2.3. Closing and Post-Closing Accounting Settlements.

(a) At or before Closing, the parties shall determine, based upon the best information reasonably available to them, the amount of the adjustments provided for in Section 2.2. If the amount of adjustments so determined which would result in a credit to Buyer exceed the amount of adjustments so determined which would result in a credit to Seller, Buyer shall receive a credit, for the amount of such excess, against the Purchase Price to be paid at Closing, and, if the converse is true, Buyer shall pay to Seller, at Closing (in addition to amounts otherwise then owed), the amount of such excess.

(b) Operating revenues and expenses shall be settled after Closing and paid in the same manner applicable to operating revenues and expenses as provided in the Operating Agreement attached as Exhibit 7.10.

(c) On or before 90 days after Closing, Buyer and Seller shall review any additional information which may then be available pertaining to the adjustments provided for in Section 2.2, shall determine if any additional adjustments (whether the same be made to account for expenses or revenues not considered in making the adjustments made at Closing, or to correct errors made in such adjustments) should be made beyond those made at Closing, and shall make any such adjustments by appropriate payments from Seller to Buyer or from Buyer to Seller in cash. Following such additional adjustments, no further adjustments shall be made under this Section 2.3, except that, any adjustments to the proration of ad valorem taxes used at Closing shall be made after such 90 day period promptly following such time as the actual ad valorem taxes become known.

Section 2.4. Payment of Adjusted Purchase Price. The Adjusted Purchase Price shall be paid to Seller as follows:

(a) At Closing, Buyer shall pay to Seller by bank transfer in immediately available funds to the account designated by Seller an amount equal to the cash portion of the Adjusted Purchase Price.

(b) Also at Closing, Buyer shall deliver to Seller completed transfer documents from VNR whereby Seller shall receive VNR units in an amount equal to the non-cash portion of the Adjusted Purchase Price.

Seller shall not be obligated to provide Buyer with access to any records or data which Seller cannot provide to Buyer without, in its opinion, breaching confidentiality agreements with other parties. All information obtained by Buyer shall be maintained in strict confidence, for use solely in connection with its evaluation of the Properties, and shall not be disclosed to any other party without Seller's prior written consent.

Section 6.2. Conduct of Operations. Seller will (i) continue the routine operation of the Properties in the ordinary course of business and as would a prudent operator; (ii) operate the Properties in material compliance with all Applicable Laws and Environmental Laws, in compliance with all oil, gas or mineral leases, and in material compliance with all Basic Documents other than such leases; and (iii) fulfill all obligations (including all obligations to make payments under leases or other Basic Documents) under such leases, and under such other Basic Documents and, in all material respects, under such Applicable Laws and Environmental Laws. Without limitation of the foregoing, the failure to perform an obligation, when such failure could result in forfeiture or termination of rights of Seller under a Basic Document, shall be considered material for purposes hereof.

Section 6.3. Restrictions on Certain Actions. Seller will not, without Buyer's prior consent:

(a) except as described on Schedule 6.3 of the Seller’s Disclosure Schedule, expend any funds in excess of twenty five thousand dollars ($25,000), or make any commitments to expend funds (including entering into new agreements which would obligate Seller to expend funds in excess of $25,000), or otherwise incur any other obligations or liabilities, in connection with the ownership or operation of the Properties after the Effective Date, other than routine expenses incurred in the normal operation of the existing xxxxx on the Oil and Gas Properties and except in the event of an emergency requiring immediate action to protect life or preserve the Properties;

(b) except where necessary to prevent the termination of an oil and gas lease or other material agreement governing Seller's interest in the Properties, propose the drilling of any additional xxxxx, or propose the deepening, plugging back or reworking of any existing xxxxx, or propose the conducting of any other operations which require consent under the applicable operating agreement, or propose the conducting of any other operations other than the normal operation of the existing xxxxx on the Oil and Gas Properties, or propose the abandonment of any xxxxx on the Oil and Gas Properties (and Seller agrees that it will advise Buyer of any such proposals made by third parties and will respond to each such proposal made by a third party in the manner requested by Buyer);

(c) sell, transfer or abandon any portion of the Properties other than items of materials, supplies, machinery, equipment, improvements or other personal property or fixtures forming a part of the Properties (and then only if the same is replaced with an item of substantially equal suitability, free of liens and security interests, which replacement item will then, for the purposes of this Agreement, become part of the Properties); or

Seller will request, from the appropriate parties (and in accordance with the documents creating such rights and/or requirements), waivers of the preferential rights to purchase, or requirements that consent to assignment be obtained, which are identified in Section 6.5 of the Seller Disclosure Schedule. Seller shall have no obligation hereunder other than to so request such waivers (i.e., Seller shall have no obligation to assure that such waivers are obtained), and if all such waivers (or any other waivers of preferential rights to purchase or requirements that consent be obtained to assignment, even if the same are not listed on such Section 6.5) are not obtained, Buyer may treat any waiver which is not obtained as a matter which causes Seller's title to not be sufficient to meet the standards set forth in Article VIII; provided, however, that if the unobtained waiver is a waiver of a preferential right to purchase, and if both Buyer and Seller agree to this treatment of such matter (and agree upon an appropriate allocation of the Purchase Price), Seller will tender (at the agreed allocated portion of the Purchase Price) the required interest in the Property affected by such unwaived preferential right to purchase to the holder, or holders, of such right who have elected not to waive such preferential right to purchase, and if, and to the extent that, such preferential right to purchase is exercised by such party or parties, such interest in such Property will be excluded from the transaction contemplated hereby and the Purchase Price will be reduced by the amount paid, or to be paid, by the party exercising such preferential right to purchase (and Seller shall collect such amount from such purchaser).

Section 6.6. Exclusive Negotiations. In consideration of the time, expense and effort to be expended by Buyer in connection with the transactions contemplated hereby, Seller will not, and will use its Reasonable Best Efforts to insure that its Affiliates and representatives do not, directly or indirectly, solicit any offer from, initiate or engage in any discussions or negotiations with, or provide any information to, any Person (other than Buyer, its Affiliates and representatives) concerning any possible proposal regarding a transaction involving the Properties.

Section 7.10. Operation of the Assets Post Closing.

At the Closing, the Parties agree to enter into mutually agreeable Operating Agreements affecting the Oil and Gas Properties on the agreed AAPL Form (Exhibit 7.10) containing the following provisions, among others:

Xxxxx Xxxxx Properties, Inc. (“LPP”) will be the Operator of the Oil and Gas Properties, however in the event that Seller (or its affiliate) sells more than fifty percent (50%) of its interest in the Oil and Gas Properties to a non-affiliated third party or parties, Buyer shall have the right to take over operations effective as of the date of the sale.
LPP shall propose the drilling of 6 xxxxx in 2008 and 7 xxxxx per year (beginning in 2009) through 2013. No more than 1 well shall be drilling at any time without the mutual consent of both parties
Should LPP fail to propose said xxxxx, Buyer shall have the right to propose same.
In the event a well is proposed and a party elects not to participate in said well, then, provided the well is drilled timely, the non-consenting party shall assign to the consenting party all of its right, title and interest in the well and in the 40 acres of leasehold around such well.
LPP shall serve as the marketing representative for Buyer for the sale of its natural gas, oil/condensate, NGL’s from processing and Buyer shall be entitled to the same benefits of pricing and other terms as if Buyer had been a signatory to said contracts. LPP shall make disbursement of revenues to Buyer within five (5) days after receipt of corresponding revenues but no later than thirty (30) days following the end of the calendar month in which production occurs.
A right of first refusal to acquire any interest subject to the Operating Agreement and being sold by a party.
In the accounting procedure to be included in the Operating Agreement, the Operator shall be entitled to the following fees for providing services to Buyer, proportionately reduced to Buyer’s interest:
- Operating/Gauging Fee: $505.00 per month per producing well (with a 4% per year escalator commencing on June 1, 2011)
As to the wellbores described on Exhibit I and for regulatory purposes only, Buyer shall have the right to use, designate and assign as much as forty acres around the borehole of each well for purposes of obtaining permits, assigning allowables and allocating allowable production. In the event the use, designation or assignment of such acreage would materially impede, impair or curtail the Operator’s rights to acquire drilling permits or to maximize allowables for xxxxx drilled on the Properties, including xxxxx the Parties may drill on acreage otherwise assigned to said well by Buyer, Buyer will take all commercially reasonable actions to designate and assign other acreage on the Properties to the borehole for the purposes described above. Seller will take all commercially reasonable actions to give effect to any designations and assignments made by Buyer as contemplated by this paragraph.

While Buyer will have the right to re-complete a well up the hole within the existing wellbore described in Exhibit I, Buyer is strictly prohibited from the following activities, without the consent of Seller:
- Deepening an existing well;
- Moving down the well to perforate or stimulate;
- Drilling a horizontal lateral from the well.

Section 7.11 Gates Production Company Participation.

Subject to certain limitations, the parties recognize and agree that the Gates Production Company, Inc. (“Gates Production”) has a contractual right to participate and acquire a ten percent (10%) working interest in all xxxxx to be drilled on lands covered by the Gates “N” Lease, which is more fully described on Exhibit II, attached hereto. If Gates Production exercises its option to participate, then the ten percent (10%) working interest shall be derived from Seller’s retained fifty-five percent (55%) interest in the Gates ”N” Lease. In the event that Gates Production elects not to participate in any given well drilled under the Gates “N” Lease (a “Non-Election Well”), then Buyer (except when Buyer is a non-consenting party) shall be obligated to acquire an additional five percent (5%) working interest equal to a 3.75% net revenue interest in that Non-Election Well. Buyer shall pay Seller $22,500 for leasehold costs associated with the additional 5% working interest in a Non-Election Well.

Further, Seller has the right, pursuant to an agreement with Gates Mineral Company, Ltd., (“Gates Mineral”) to drill up to two additional xxxxx on the Gates “Amended-Consolidated” Lease (which is more fully described on Exhibit III) in lieu and satisfaction of Seller’s drilling obligation on a lease between Seller and Gates Mineral Company, Ltd. which is not a part of this transaction. In the event Seller chooses to drill such obligation xxxxx on the Gates “Amended-Consolidated” Lease, Gates will have the right to participate and acquire a ten percent (10%) working interest in such xxxxx. If Seller chooses to drill such obligation xxxxx on the Gates “Amended-Consolidated” Lease and if Gates elects to participate for its ten percent (10%) share, then the ten percent 10% working interest shall be derived by deducting five percent (5%) from Buyer and five percent (5%) from Seller. In such a case, Seller shall pay or credit Buyer in the amount of $22,500 for leasehold costs associated with the five percent (5%) working interest derived from Buyer.

Section 7.12 Audit.

Within 45 days after Closing, Seller shall cause its outside auditor to audit the revenues and direct operating expenses for the Oil and Gas Properties for the calendar year 2007. Such outside auditor shall agree that said financial data and related audit opinion can be used by VNR in its public filings. The cost of preparing said audit shall be paid by Buyer.

(c) Removal of Legend. The Seller may request VNR to remove the legend described in Section 7.15(b) from the certificates evidencing the VNR Units by submitting to VNR such certificates, together with an opinion of counsel reasonably satisfactory to VNR to the effect that such legend is no longer required under the Securities Act or applicable state laws, as the case may be. VNR shall cooperate with the Seller to effect the removal of such legend.

ARTICLE XI

SURVIVAL OF REPRESENTATIONS, WARRANTIES AND COVENANTS; INDEMNIFICATION

Section 11.1. Survival.

(a) The representations and warranties of the parties hereto contained in this Agreement or in any certificate, instrument, or document delivered pursuant hereto shall survive the Closing, regardless of any investigation made by or on behalf of any party, provided that (i) any representation and warranty of Seller contained in Sections 4.7 through 4.18 pertaining to the payment of (x) royalties and (y) severance and other similar taxes shall survive until the second anniversary of the Closing Date and (ii) all other the representations and warranties of Seller contained in Sections 4.7 through 4.18 shall survive until the first anniversary of the Closing Date (such anniversary date and time of expiration called a "Survival Date"). From and after a Survival Date, no party hereto shall be under any liability with respect to any representation or warranty to which such Survival Date relates, except with respect to matters as to which notice has been received in accordance with Section 11.1(b).

(b) No party hereto shall have any indemnification obligation pursuant to this Article XI or otherwise in respect of any representation, warranty or covenant unless it shall have received from the party seeking indemnification written notice of the existence of the claim for or in respect of which indemnification in respect of such representation, warranty or covenant is being sought, and such written notice is given on or before the applicable Survival Date. Such notice shall set forth with reasonable specificity (i) the basis under this Agreement, and the facts that otherwise form the basis of such claim, (ii) the estimate of the amount of such claim (which estimate shall not be conclusive of the final amount of such claim) and an explanation of the calculation of such estimate, including a statement of any significant assumptions employed therein, and (iii) the date on and manner in which the party delivering such notice became aware of the existence of such claim.

(c) From the Closing Date through the Survival Date, any claim for indemnification for any title defect(s) by Buyer from Seller pertaining to Section 4.7 (“Basic Documents”) is only enforceable to the extent the aggregate sum of all claims for title defect(s) is in excess of 2.5% of the Purchase Price.

Section 11.2. Seller's Indemnification Obligations. Seller shall, on the date of Closing, agree (and, upon delivery to Buyer of the Conveyance, shall be deemed to have agreed), subject to the limitations and procedures contained in this Article XI, following the Closing, to indemnify and hold Buyer, its Affiliates and its and their respective successors and permitted assigns and all of their respective stockholders, partners, members, managers, directors, officer, employees, agents and representatives harmless from and against any and all claims, obligations, actions, liabilities, damages or expenses (a) resulting from any misrepresentation or breach of any warranty, covenant or agreement of Seller contained in this Agreement or any certificate delivered by Seller at the Closing, (b) relating to the Excluded Assets, or (c) relating to the ownership or operation of the Properties before the Effective Date.

Section 11.3. Buyer's Indemnification Obligations. Buyer shall, on the date of Closing, agree (and, upon delivery to Buyer of the Conveyance, shall be deemed to have agreed), subject to the limitations and procedures contained in this Article XI, following the Closing, to indemnify and hold Seller harmless from and against any and all claims, obligations, actions, liabilities, damages, costs or expenses, (collectively, "Seller's Losses") (a) resulting from any misrepresentation or breach of any warranty, covenant or agreement of Buyer contained in this Agreement or any certificate delivered by Buyer at the Closing, or (b) relating to Buyer's ownership and operation of the Properties after the Effective Date.

Section 11.4. Indemnification Proceedings. In the event that any claim or demand for which a party (an "Indemnifying Party"), would be liable to the another party under Section 11.2 or Section 11.3 (an "Indemnified Party") is asserted against or sought to be collected from an Indemnified Party by a third party, the Indemnified Party shall with reasonable promptness notify the Indemnifying Party of such claim or demand, but the failure so to notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations under this Article XI, except to the extent the Indemnifying Party demonstrates that the defense of such claim or demand is materially prejudiced thereby. The Indemnifying Party shall have 30 days from receipt of the above notice from the Indemnified Party (in this Section 11.4, the "Notice Period") to notify the Indemnified Party whether or not the Indemnifying Party desires, at the Indemnifying Party's sole cost and expense, to defend the Indemnified Party against such claim or demand; provided, that the Indemnified Party is hereby authorized prior to and during the Notice Period to file any motion, answer or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnifying Party and not prejudicial to the Indemnifying Party. If the Indemnifying Party elects to assume the defense of any such claim or demand, the Indemnified Party shall have the right to employ separate counsel at its own expense and to participate in the defense thereof. If the Indemnifying Party elects not to assume the defense of such claim or demand (or fails to give notice to the Indemnified Party during the Notice Period), the Indemnified Party shall be entitled to assume the defense of such claim or demand with counsel of its own choice, at the expense of the Indemnifying Party. If the claim or demand is asserted against both the Indemnifying Party and the Indemnified Party and based on the advice of counsel reasonably satisfactory to the Indemnifying Party it is determined that there is a conflict of interest which renders it inappropriate for the same counsel to represent both the Indemnifying Party and the Indemnified Party, the Indemnifying Party shall be responsible for paying separate counsel for the Indemnified Party; provided, however, that the Indemnifying Party shall not be responsible for paying for more than one separate firm of attorneys to represent all of the Indemnified Parties, regardless of the number of Indemnified Parties. If the Indemnifying Party elects to assume the defense of such claim or demand, (i) no compromise or settlement thereof may be effected by the Indemnifying Party without the Indemnified Party's written consent (which shall not be unreasonably withheld) unless the sole relief provided is monetary damages that are paid in full by the Indemnifying Party and (ii) the Indemnifying Party shall have no liability with respect to any compromise or settlement thereof effected without its written consent (which shall not be unreasonably withheld).

Section 11.5. Indemnification Exclusive Remedy. Indemnification pursuant to the provisions of this Article XI shall be the exclusive remedy of the parties hereto for any misrepresentation or breach of any warranty, covenant or agreement contained in this Agreement or in any closing document executed and delivered pursuant to the provisions hereof or thereof, or any other claim arising out of the transactions contemplated by this Agreement.

Section 11.6. Limited to Actual Damages; No Consequential Damages. The indemnification obligations of the parties pursuant to this Article XI shall be limited to actual Damages and shall not include incidental, consequential, indirect, punitive, or exemplary Damages, provided that any incidental, consequential, indirect, punitive, or exemplary Damages recovered by a third party (including a Governmental Entity, but excluding any Affiliate of any party) against a party entitled to indemnity pursuant to this Article XI shall be included in the Damages recoverable under such indemnity.

ARTICLE XII

MISCELLANEOUS MATTERS

Section 12.1. Dispute Resolution.

(a) Any and all claims, disputes, controversies or other matters in question arising out of or relating to this Agreement, any provision hereof, the alleged breach of any such provision, or in any way relating to the subject matter of this Agreement or the relationship among the parties created by this Agreement, involving the parties, their affiliates and/or their respective representatives (all of which are referred to herein as "Disputes"), even though some or all of such Disputes allegedly are extra-contractual in nature, whether such Disputes sound in contract, tort, or otherwise, at law or in equity, under state or federal law, whether provided by statute or the common law, for damages or any other relief, shall be resolved solely in accordance with this Section 12.1.

(b) If a Dispute occurs that the senior representatives of the parties responsible for the transaction contemplated by this Agreement have been unable, in good faith, to settle or agree upon within a period of 15 days after such Dispute arose, the Seller shall nominate and commit one of its senior officers, and Buyer shall nominate and commit one of its senior officers, to meet at a mutually agreed time and place not later than 30 days after the Dispute has arisen to attempt to resolve same. If such senior management have been unable to resolve such Dispute within a period of 15 days after such meeting, or if such meeting has not occurred within 45 days following such Dispute arising, then any party shall have the right, by written notice to the other, to resolve the Dispute by arbitration in accordance with the provisions of Section 12.1(d).

(d) Any Dispute that is not resolved pursuant to the foregoing provisions of this Section 12.1 shall be settled exclusively and finally by arbitration in accordance with this Section 12.1(d).

(i) Such arbitration shall be conducted pursuant to the Federal Arbitration Act, except as expressly provided otherwise in this Agreement. The validity, construction, and interpretation of this Section 12.1(d), and all procedural aspects of the arbitration conducted pursuant hereto, including the determination of the issues that are subject to arbitration (i.e., arbitrability), the scope of the arbitrable issues, allegations of "fraud in the inducement" to enter into this Agreement or this arbitration provision, allegations of waiver, laches, delay or other defenses to arbitrability, and the rules governing the conduct of the arbitration (including the time for filing an answer, the time for the filing of counterclaims, the times for amending the pleadings, the specificity of the pleadings, the extent and scope of discovery, the issuance of subpoenas, the times for the designation of experts, whether the arbitration is to be stayed pending resolution of related litigation involving third parties not bound by this Agreement, the receipt of evidence, and the like), shall be decided by the arbitrators. The arbitration shall be administered by the American Arbitration Association (the "AAA"), and shall be conducted pursuant to the Commercial Arbitration Rules of the AAA (the "Rules"), except as expressly provided otherwise in this Agreement. The arbitration proceedings shall be subject to any optional rules contained in the Rules for emergency measures and, in the case of Disputes with respect to amounts in excess of $1 million, optional rules for large and complex cases.

(ii) The arbitrators shall permit and facilitate such discovery as they determine is appropriate in the circumstances, taking into account the needs of the parties and the desirability of making discovery expeditious and cost-effective. Such discovery may include pre-hearing depositions, particularly depositions of witnesses who will not appear personally to testify, if there is a demonstrated need therefore. The arbitrators may issue orders to protect the confidentiality of proprietary information, trade secrets and other sensitive information disclosed in discovery.

(iii) All arbitration proceedings hereunder shall be conducted in San Antonio, Bexar County, Texas or such other mutually agreeable location.

(iv) All arbitration proceedings hereunder shall be before a panel of three (3) arbitrators appointed in accordance with the Rules consisting of Persons (which can include lawyers) having at least ten (10) years of experience in or relating to the oil and gas industry.

(v) In deciding the substance of the Dispute, the arbitrators shall refer to the substantive laws of the State of Texas for guidance (excluding choice-of-law principles that might call for the application of the laws of another jurisdiction). Matters relating to arbitration shall be governed by the Federal Arbitration Act.

(vi) The parties shall request the arbitrators to conduct a hearing as soon as reasonably practicable after appointment of the third arbitrator, and to render a final decision completely disposing of the Dispute that is the subject of such proceedings as soon as reasonably practicable after the final hearing. The parties shall instruct the arbitrators to impose time limitations they consider reasonable for each phase of such proceeding, including, without limitation, limits on the time allotted to each party for the presentation of its case and rebuttal. The arbitrators shall actively manage the proceedings as they deem best so as to make the proceedings fair, expeditious, economical and less burdensome than litigation. To provide for speed and efficiency, the arbitrators may: (i) limit the time allotted to each party for presentation of its case; and (ii) exclude testimony and other evidence they deem irrelevant or cumulative.

(vii) Notwithstanding any other provision in this Agreement to the contrary, the parties expressly agree that the arbitrators shall have absolutely no authority to award consequential, incidental, special, treble, exemplary or punitive damages of any type under any circumstances regardless of whether such damages may be available under Applicable Law, or under the Federal Arbitration Act or the Rules.

(viii) The parties agree that there shall be no transcript of any hearing before the arbitrators. The parties shall request that final decision of the arbitrators be in writing, be as brief as possible, set forth the reasons for such final decision, and if the arbitrators award monetary damages to either party, contain a certification by the arbitrators that they have not included any incidental, special, treble, exemplary or punitive damages. To the fullest extent permitted by law, the arbitration proceeding and the arbitrators' decision and award shall be maintained in confidence by the parties and the parties shall instruct the arbitrators to likewise maintain such matters in confidence.

(ix) The fees and expenses of the arbitrators shall be borne equally by Sellerand Buyer, but the decision of the arbitrators may include such award of the arbitrators' fees and expenses and of other costs and attorneys' fees as the arbitrators determine appropriate (provided that such award of costs and fees may not exceed the amount of such costs and fees incurred by the losing party in the arbitration).

(x) The decision and award of the arbitrators shall be binding upon the parties and final and nonappealable to the maximum extent permitted by law, and judgment thereon may be entered in a court of competent jurisdiction and enforced by any party as a final judgment of such court.
